Patented Dec. 16, 1930 UNITED STATES JP IENTO IC DONALD B. MCDONALD, oroUIT AN, snonsm BABR L-HEAD-FAs NI G' iirEANs Application filed March 19,1929. Serial No. 348,298.

This inventionvrelates to certain new and.

useful barrel head fastening means and is intended to Overcome certam difliculties encountered m devices of th1s character as, for

example, is shown in the patent to Mote et' al 1,197,387, September 5, 1916. In devices of this character it is desirable that when the barrel or receptacle is turned down that such semi-fluid contents as rosin etc. will readily flow out if the barrel headis removed. In the the barrel head fastening means while at the same time making it easy to operate.

Another object of the invention is to provide a wedging fit between the barrel'head and stavesand the fastening means are more or less elastic to take up any wear between the periphery of the barrel head and the staves.

With these and other objects in view which will be developed as the description proceeds I will now describe my invention inconnection with the accompanying drawings in which, r

Figure 1 is a top plan view of my invention with the head partly broken away to disclose the clamping means.

Figure 2.is a fragmentary section on the line 22 of'Figure 1.

Figure 3 is a bottom view of the barrel head above the barrel sufliciently to act as a handle to cheapen and simplify the construction of,

to the head 1y I bolt a bar 3. This bar extends to be; clasped and thehead given a turning motion after the ends 55 of a bar 4 have been started under the offsets 6 6 formed integral with a 'ring 7 The offsets 6-6 are preferablyjslightly springy in their action and may be inclinedto the plane of the; ring as shown in Figure 2 although such: inclina tion is not necessary. t f r 1 The bolts,9.9 extend through the bar 3 on top of the head through the head '1 and the bar .4 asbestshown in Figure 2. v 'f' Theba-r't may also be somewhat springy to takeup any wearjbetween the head andtop of the bar'rel staves. I It will be observed that whenthe barrel head is removed and the bar,-

jrel turned down the ring offers little or no obstruction to the outflow of material froin the barrel and the ringmay be left inthe barrel after having been once inserted'therein.

It will'be observed that'by. my construe tion while the head preferably rests on the ring the barrel head need not rest directly on the ring but some distance above the ring and as the periphery of the head wears or the inner portions of the ends of the staves'be come worn the head may still be held tightly in the end of the barrel by my fastening means. When the head is inserted in the end of the barrel and the wedge shaped ends 5 of the bar 4; comes against the lower edge of the offset 6 as the head is turned slightly it will tighten the parts and makes, tight fit between the periphery of the head and the staves or the head and ring even though these parts become more or less worn or displaced. The operation of my clamping means is apparent from the foregoing but to summarize the same the ring 7 is placed in the barrel groove and the barrel head inserted in the upper end of the barrel which 9 is preferably larger at the extreme end of the barrel than it is farther down at or near the ring '7. Having first placed the head in the open ended barrel it is turned until the wedge shaped ends 5 catch on the offsets 6 of the ring 7 and pull the head downwardly into the end of the barrel and ordinarily rests on the ring and by reason of the wedge V shaped ends 5 cooperating with the offsets 6 t and the barrel head'may thus be firmly held to the barrel to stand any reasonable internal pressure. It is apparent that lnstead of having the barrel end slightly tapering the head may be tapered slighty so as to maintain the fit between the periphery of the head and the open end of the barrel.

Having thus described my invention what I claim is:

1. A container head fastening means com- 10 prising a container having an internal groove near its end, an elastic ring fitting into the groove and substantially enclosed in the groove said ring having ofisets extendinginwardly from the groove and a head fitting 15 snugly into the end of the container above the rim said head having attached thereto on its underside a bar with wedge shaped ends approximately at the outer periphery of the underside of the head and adapted to co- 20 operate with the offsets on the rim to pull the head into the end of the container and tighten the fit between the head and the inte rior of the container. v

2. A container having a groove near its m: end, a ring adapted to fit in said groove and to be substantially enclosed therein said ring having diametrically oppositely disposed oilsets extending inwardly from said ring and in substantially the same plane as the ring 3Q and a head for the container having on its inner surface, a bar with wedge shaped ends 7 extending circumferentially of the head and terminating at approximately the outer periphery of the head.

In testimony whereof I afiix my signature.
